A nurse is assessing a 45-year-old client with a 3-year history of rheumatoid arthritis. Which assessment finding would be most characteristic of this condition?
1Bilateral symmetrical joint swelling and stiffness, particularly in the hands and wrists, that is worse in the morning and lasts over an hour.✓ 정답
2Unilateral joint pain that primarily affects weight-bearing joints such as the hips and knees, worse with activity and improves with rest.
3Joint stiffness that occurs after periods of inactivity but resolves within 15-30 minutes of movement, typical of osteoarthritis.
4Asymmetrical joint involvement with characteristic skin changes including butterfly rash across the cheeks, suggestive of systemic lupus erythematosus.
해설
Bilateral symmetrical joint swelling and stiffness in small joints like hands/wrists with morning stiffness >1 hour is characteristic of RA. Other options describe features of osteoarthritis, lupus, or mechanical pain.
Core Nursing ExplanationKey Concept Analysis: This question tests the ability to differentiate the cardinal clinical features of Rheumatoid Arthritis (RA) from other common joint disorders. RA is a chronic, systemic autoimmune disease characterized by inflammation of the synovial membrane (synovitis), leading to joint destruction. Its hallmark is a symmetrical, inflammatory polyarthritis.
Answer Rationale: Key Point! The correct answer describes the classic presentation of RA: Bilateral, symmetrical involvement of small joints (metacarpophalangeal (MCP), proximal interphalangeal (PIP) joints, wrists), with morning stiffness lasting more than one hour. This prolonged stiffness reflects the inflammatory nature of the disease, where synovial fluid and tissue edema accumulate during periods of rest. The symmetry is a key differentiator from other conditions.
Distractor Analysis:
Watch out for confusion! Option ② describes Osteoarthritis (OA) or mechanical joint pain. OA is degenerative, typically asymmetric or unilateral, affects weight-bearing joints, and pain worsens with use and improves with rest. Morning stiffness in OA is brief (<30 minutes).
Option ③ explicitly describes the "gelling" phenomenon of Osteoarthritis, where stiffness after inactivity resolves quickly with movement, contrasting sharply with RA's prolonged morning stiffness.
Option ④ describes features of Systemic Lupus Erythematosus (SLE), notably the malar (butterfly) rash and often asymmetrical arthralgia/arthritis. While SLE can cause joint pain, the pattern and associated systemic symptoms differ from RA.
Related Concepts: RA is associated with systemic manifestations like rheumatoid nodules, fatigue, fever, and can affect extra-articular organs (lungs, heart, eyes). Laboratory findings often include positive Rheumatoid Factor (RF) and Anti-Cyclic Citrullinated Peptide (anti-CCP) antibodies. Nursing care focuses on pain management, preserving joint function, patient education on energy conservation and medication adherence (e.g., DMARDs - Disease-Modifying Antirheumatic Drugs).

Worsens with activity, improves with rest
Systemic Symptoms
Common (fatigue, fever, weight loss)
Rare
Characteristic Deformity
Ulnar deviation, swan-neck, boutonnière
Heberden's nodes (DIP), Bouchard's nodes (PIP)
Anatomy, Physiology & Pharmacology Points
Pathophysiology: In RA, CD4+ T-cells activate B-cells and macrophages, leading to synovial hyperplasia and pannus formation. This pannus invades and destroys cartilage and bone.
Pharmacology: First-line treatment often includes DMARDs like Methotrexate (folic acid supplement required to reduce side effects). Biologic agents (e.g., TNF-alpha inhibitors like Etanercept) target specific inflammatory pathways. NSAIDs and corticosteroids are used for symptom control.
Memory Tips
RA Mnemonic: "RA is Symmetric, Systemic, and Stiff in the morning."
Joint Pattern: RA loves small joints (Hands, Wrists, Feet). OA loves weight-bearing joints (Hips, Knees, Spine) and finger end-joints (DIP).
High-Frequency NCLEX Topics
NCLEX frequently tests the differentiation between RA and OA, especially the pattern of joint involvement and the nature/duration of stiffness. Be prepared to select priority nursing interventions for a client with RA, such as promoting rest during acute flares, applying warm or cold compresses for stiffness/pain, and teaching about joint protection techniques.
Watch Out for Question Variations!
Instead of asking for an assessment finding, the question might ask: "The nurse is teaching a client newly diagnosed with RA. Which statement by the client indicates understanding of the disease?" (Correct answer would relate to managing morning stiffness or the chronic, systemic nature).
The question could present lab results (RF, anti-CCP, ESR) and ask which disease they are most indicative of.
It could shift to priority nursing diagnosis: For a client with active RA, "Acute Pain" and "Impaired Physical Mobility" are often high priority.
Nursing Clinical Practice GuideClinical Scenario: You are the day-shift nurse for Ms. Johnson, 45, admitted for an exacerbation of her RA. She reports severe morning stiffness in both hands and wrists that takes nearly two hours to "loosen up." Her fingers appear swollen and warm to the touch.
Nursing Intervention Strategy:
1. Assessment: Perform a comprehensive joint assessment using a systematic approach (inspect for swelling, redness, deformity; palpate for warmth, tenderness; assess range of motion and functional status). Use a pain scale. Assess for systemic symptoms (fatigue, fever) and extra-articular manifestations.
2. Planning & Implementation:
Pain & Stiffness Management: Schedule morning activities later if possible. Encourage a warm shower or paraffin wax baths upon waking to ease stiffness. Administer prescribed analgesics/NSAIDs before planned activity.
Joint Protection: Teach use of adaptive devices (built-up utensils, jar openers). Encourage use of larger, stronger joints (e.g., push doors with shoulder, not hand).
Activity & Rest Balance: Promote rest during acute inflammatory flares, but encourage gentle, regular range-of-motion exercises to maintain function. Refer to occupational/physical therapy.
Medication Education: Stress the importance of adhering to DMARDs (e.g., Methotrexate) even when feeling better, as they modify disease progression. Review side effects (e.g., liver toxicity, bone marrow suppression) and monitoring needs (regular CBC, LFTs).
Patient Safety and Precautions: Corticosteroids (e.g., Prednisone) increase infection risk—monitor for signs. Immunosuppressants and biologics also require vigilant infection monitoring. Avoid overuse of joints during acute inflammation to prevent further damage.
Nursing Procedure & Medication FlowAdministering Methotrexate (a common DMARD):
1. Verify order, dose, and route (often oral or subcutaneous weekly).
2. Check baseline CBC and Liver Function Tests (LFTs) results.
3. Administer as prescribed. For oral route, it is typically taken once a week (critical teaching point to prevent overdose).
4. Educate patient to take folic acid supplement as prescribed to reduce mucosal and GI side effects.
5. Monitor for side effects: mouth ulcers, nausea, easy bruising/bleeding (thrombocytopenia), signs of infection (neutropenia), hepatotoxicity.
A Word from Your Senior Nurse
"Remember, RA is more than just 'achy joints.' It's a systemic disease that affects a person's entire life. Your keen assessment skills in identifying the pattern of stiffness and swelling are the first step in validating the patient's experience and guiding care. In clinical practice, you'll see the profound fatigue that accompanies RA flares. Your empathy and teaching on energy conservation can be as valuable as any medication. For the NCLEX, lock in that 'bilateral, symmetrical, morning stiffness >1 hour' triad—it's a surefire way to spot RA in a question!"
